  2. Where we are now: The site is back up and running! The character set encoding issue has been fixed so old posts should now look ok. I am currently working on themes/skins etc and I will be deleting the temporary green skin very soon as it has many issues. I will do a very quick variation on the stock blue skin first just to get a light-grey background and san-serif font, and I will set this as default. Later this week I will hopefully add a professional third-party skin in pfm colours (life is way too short to do this crap myself, and I've found one I really like than needs next to no tweaking). We are getting there slowly...

  3. May I please request people check and update their email address if it is out if date. I ask as I’m getting countless bounce errors as the server fails to send notifications through etc. I’ll eventually figure out how to send these to a black hole somewhere, but it makes sense to address it at source as quite a few folk are obviously not getting the thread and conversations notifications they have set in their preferences.

  4. Things you need to know about the new ‘Conversations’ PM system:

    a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.

    b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.

Meridian 104 Tuner Q?

Discussion in 'd.i.y.' started by neiljadman, Sep 17, 2009.

    Noting much really - it works great - just that the bulb illuminating the meter is out - anyone know what it is?

    OK, fixed - a standard white LED with a 1N4148 diode across it works wonders....

    Care to show any more of the 104? It's supposed to be very good indeed, and finding a nice one is on my 'want to try' list...

    I'll post some pics... and yes they really are very good indeed...open, accurate and good bass. So good I have two...and I listen to it more the the NAT01/NAPST if that says anything.

    Like everything 100 series Meridian they were strangled by the "power daisy chain" and really benefit from being connected directly to power.

    This one started life as UK spec unit and was converted to US when I came over here 20 years ago. I just recapped it a few months ago and at the time didn't bother to replace the lamp as I couldn't find one at a high enough voltage. It's a T5 I think - anyway a 5mm LED slots right in, and runs of 32vAC directly after the transformer - hence the diode across the LED to block the reverse voltage.

    But having 5 tuners a I have decided to part with this one - hence the desire to re-illuminate the meter. And the LED works remarkably well and should be more durable than another incandescent bulb.

    I'll post some picx as soon as they have uploaded to photobucket.

    Nice.

    I hankered after one of those after I bought the 101 preamp (many, many moons ago)

    I'll second the request, especially since this is the DIY forum.

    What's that brown thing under the boards that looks like a paper bag?

    Paper bag probably not, but treated paper of some sort it is. It's a feature of all 100 series units and I always assumed it's to prevent any accidental short from the underside of the board to the case things - are all very close together in these diminutive cases.

    Quaint. Adds a nice "cottage industry" touch.
